duagon MC50M

DIN-Rail modular computer and IO system from railway leaders

Manufacturer: duagon MEN
duagon MC50M

The MC50M is a modular computer for embedded applications in transportation, e.g., trains, buses or commercial vehicles. The computing platform features an Intel Atom E3900 series CPU with low power dissipation and scalability in performance and memory. The MC50M is the ideal basis for functions such as security gateway, predictive maintenance, CCTV or ticketing system, or to act as a diagnostics server.

Modular System for Easy Configuration

The MC50M can be a stand-alone product, but due to MEN's modular concept, it offers flexible built-to-order configurations. The box can be easily combined with prefabricated extension modules, providing additional features and short delivery times. In the modular system, the data transfer between the modules as well as the power supply of the individual components takes place via the extension connectors standardized by MEN.

Extension modules can provide application-specific functions like wireless communication (LTE advanced, WLAN, GNSS), MVB, CAN bus, or other I/O. A removable storage shuttle can support the integration of one or two 2.5" SATA HDDs/SSDs. With a PSU extension module, ultra-wide range isolated power supply from 24 V DC to 110 V DC nominal (EN 50155) is available.

Power Saving Design and Security Features

The board management controller provides enhanced reliability and reduced downtime. The Trusted Platform Module supports security and encryption features. With the ignition switch for remote control of booting and shutdown, the platform provides additional features for power saving.

Flexible System Installation

Various mounting options facilitate the integration of the box into an existing environment. The standard 35 mm DIN Rail mounting offers space-saving mounting of all system modules on a single rail. Wall mounting and mounting in a 19" rack using adaption brackets are an option.

The aluminium housing with cooling fins provides conduction cooling for fanless operation. MC50M has no moving parts, making it maintenance-free.

In-Vehicle Qualified and Long-Term Availability

The CPU module is qualified for rolling stock and wayside applications as well as for road vehicles (ECE R10). Long term availability of 15 years from product start minimizes life-cycle management by making the MC50M available at least for this period of time.
